OnePlus Buds Pro 3

Two earbuds (one pair) with a charging case; the box lists ear tips in XS, S, M and L pairs, with M pre-installed. OnePlus says the four sizes ensure the best possible fit, and that fit quality varies with the shape and size of the listener's ears. The ear tip material is not stated.

Each earbud, as stated on the UK page for this UK SKU; the case weighs 50.57 g (total 61.13 g). The US page (US SKU 5481158571) states 5.29 g per earbud, 50.62 g case and 61.20 g total.

OnePlus: 'Excludes charging case.' Water and dust resistance may be reduced as the device ages; liquid and dust damage are not covered under warranty.

UK: 50.57 g; US: 50.62 g. The selected SKU is UK; the source discrepancy is unexplained. Do not average the figures, assert physical equivalence across regions or interpret case weight as the earbuds-and-case total.

UK: 61.13 g; US: 61.20 g. These are published total values, not newly calculated sums. The regional difference remains unexplained.

The UK and US specification tables list Bluetooth 5.4 with Steady Connect. The overview Bluetooth 5.4 tile is captioned “When paired with the OnePlus 12 or OnePlus 13 series phones”; preserve this published scope discrepancy without assuming all hosts gain Bluetooth 5.4 features. Steady Connect needs compatible OnePlus phones. Fast Pair is limited to OnePlus 6 series and later devices running Android 11 or later. Case charging is separate from audio.

OnePlus Test Laboratory claims at 50% volume and the stated codec/mode. Keep the agreeing figures positive. The conflicting playback claim with the case, AAC and ANC on is separately nullable; neither 25 nor 25.5 hours may establish a requirement match, runtime winner or upgrade gain. A 10-minute fast charge advertises up to 13 hours with earbuds and case. Talk time with AAC, ANC on and 50% volume is 4 hours for earbuds or 17 hours with the case.

Only when paired with select OnePlus phone models with Pro Gaming mode enabled.

LHDC 5.0 Hi-Res: 1 Mbps bit rate, 24-bit/192 kHz. Hi-Res is supported on devices with LHDC 4.0 and above (OnePlus phones with Android 12 and above via 'Earbuds Function'; other Android 7.0 and above via the HeyMelody app) and is not supported on iOS devices.

The source describes charging, not USB audio or data operation. Compatible charger power and a cable-audio mode are not established.

Wireless charging and reverse wireless charging from compatible phones such as the OnePlus 12 are explicitly advertised. The pages do not name a wireless charging standard or prove every charger works.

Conflicting exact manufacturer sources: the UK and US specifications state 25.5 hours; the UK overview and its footnote state 25 hours. Both say AAC, ANC on and 50% volume. Neither figure is selected as resolved. · Music playback with the case, AAC, ANC on and 50% volume. Manufacturer test claim; the exact sources disagree on this duration.

The table gives two values but does not explicitly assign them to a named driver or a headphone input/load condition. Do not invent a woofer/tweeter assignment or amplifier compatibility result.

Buds 4 names a 1 mW input but no frequency or test fixture. Buds Pro 3 names 1 kHz and the literal “Input: -10 dB IEC711” notation, without identifying that input in volts or milliwatts. These do not provide sensitivity on the same basis; do not convert or rank them.

Woofer: dual-magnet dynamic driver with a 30-layer ceramic-metal diaphragm; tweeter: planar voice coil with a flat diaphragm.

The overview explicitly advertises on-device rendering for Android and iOS. Set through Earbuds Function on OnePlus phones running Android 11 or later, or through HeyMelody for other iOS/Android 7 or later users. The positive head-tracking claim has separate platform scope.

The overview explicitly advertises dynamic head tracking. Its note expressly supports spatial audio with head tracking through Earbuds Function on OnePlus phones running Android 11 or later. For other iOS/Android 7 or later users with HeyMelody, it only expressly says spatial audio; head-tracking support on those hosts remains unresolved.

No frequency, input reference, weighting or explicit maximum label is supplied in this row. Do not reinterpret as maximum SPL or sensitivity.

The Audio table does not explicitly assign this rating to an individual driver or define a continuous/peak basis. No power-handling or sound-quality ranking is established.

Real-time adaptive ANC advertised up to 50 dB, based on OnePlus Test Laboratory results. The overview’s 2× voice-cancellation claim compares with OnePlus Buds Pro 2, not Buds 4. The wind-fluctuation disclaimer is attached to AI noise-cancellation context; do not expand it into a newly measured ANC result. A 1-second long press toggles ANC.

3 mics + VPU (Voice Pick Up Bone Sensor) with the AI Clear Call algorithm; the overview labels them feed-forward, talk and feed-back mics. OnePlus does not state whether the count is per earbud.

The exact table names VPU (Voice Pick Up Bone Sensor); overview describes capturing bone-conducted voice. This is a component claim, not independent call-quality proof.

Buds4 gives no dBV/Pa reference; Pro3 explicitly gives dBV/Pa. These different bases cannot establish a microphone-performance difference.

Golden Sound is set in 'Earbuds Function' on OnePlus phones with Android 11 and above; other users (iOS / Android 7.0 and above) need the HeyMelody app. The specification page also lists OTA updates.

Activating Find My Earbuds makes a dropped earbud emit sounds.

Integrated IMU sensors monitor activity and give posture alerts.

Real-time in-person translation when used with select OnePlus phones; available on devices with Oxygen OS 15.0.1 and above.

Started with a 3-second long press.

Custom settings via the app. The specification page also lists a voice assistant.
